How do I fix the error which I get at last? I am on ubuntu 14.04.
Creating a new rails application without mysql works fine. But, when I put mysql with a -d flag. I am getting this error. Can someone please explain what's the problem?
On running gem install mysql2 -v '0.3.18' it gave :
ERROR: While executing gem ... (Errno::EPERM)

I need to connect to a MySQL database. I've found a gem called "mysql" and one called "mysql2". I tried installing and using both gems and got a message like this:
cannot load such file -- mysql (LoadError)

Which gem should I use and what am I doing wrong?
I'm using Ruby 2.1.7.
I have a rails application which is running on Rails 3.2.8 and Ruby 1.9.3.I am also using Mysql server as database.
When I run rake db:migrate, I get the following error:
rake aborted!
Incorrect MySQL client library version! This gem was compiled for 6.0.0 but the
client library is 5.5.34.

How do I solve this issue?
Any help is appreciated..
Since you are using windows, you have two options to solve this :
Either use 2.8.1 version of mysql gem by writing
gem 'mysql', '2.8.1' #in your gemfile
run
bundle install
OR
Simply use mysql2 gem
gem 'mysql2'
and put the libmysql.dll file in installed MySQL bin directory with the one which you can get from the below link in location lib/libmysql.dll from
http://dev.mysql.com/get/Downloads/Connector-C/mysql-connector-c-noinstall-6.0.2-win32.zip/from/pick
gem 'mysql2' ## gemfile
rm Gemfile.lock
bundle install
rake db:drop && rake db:create
I can't seem to get mysql to work with my new rails app at all... terminal copy below:

What else should I try before reinstall Lion?
Look into using Ruby Version Manager (called rvm) and then update Ruby. Try using ver 1.9 of ruby or higher. Don't reinstall your OS. If anything, remove rails, remove ruby. Install rvm, install ruby 1.9, install rails. If you follow that recipe, all should be well.
Configuring Rails to work with MySQL will happen through changing the file:
myappname/config/database.yml
Good information is here: How do I set MySQL as the default database in Rails 3?
... and here: Create a new Ruby on Rails application using MySQL instead of SQLite
Get used to looking at the Rails guides. Examples like this: http://guides.rubyonrails.org/getting_started.html#configuring-a-database are all you need to get going.

Unable to start rails server but my mysql version is different and that doesn't solve it even with changing 0.2.6 to 0.3.11
The issue is that Ruby can't find the libraries necessary to build the MySQL gem, there are many ways to fix this but since it looks like you're just starting up on Ruby, I think it's worth to prepare your environment so you don't see this kind of stuff again, here are the steps:
First I would recommend you to install Homebrew, with Homebrew installed, install MySQL:
brew install mysql
This will install MySQL in your machine including the necessary libraries to build the MySQL gem when you need it.
Then you should to install RVM to install your rubies (before installing RVM you need to run brew install git). Once you install RVM, you can start installing any rubies you would like to.
And then you ask, why can't you use the built in Ruby? Rails will drop support for the Ruby 1.8.* branch on 4.0 and the community in general uses RVM (or rbenv) to install and manage rubies installed to your machine.

when i try to install activerecord-mysql2-adapter by :gem install activerecord-mysql2-adapter
ERROR: Could not find a valid gem 'activerecord-mysql2-adapter' (>= 0) in any repository
please help me
thanks
The problem is because you are trying to install the latest version of mysql2 which is incompatible with rails 3.0.x version
SO, in your Gemfile change the line for mysql2 gem for this:
gem 'mysql2', '< 0.3'
then bundle command
and then when the new mysql2 gem file ( i think is 0.2.7 ) you will solve the problem.
if still not working try this too:
sudo install_name_tool -change libmysqlclient.18.dylib /usr/local/mysql/lib/libmysqlclient.18.dylib /Users/YOUR_USER_NAME/.rvm/gems/1.8/gems/mysql2-0.2.7/lib/mysql2/mysql2.bundle
gem 'mysql2', '< 0.3' is the only way on Rails 3.0.7 (before 3.1)
UPDATE: sorry, that was not the case also, did't work either, there is a better way:
vendor/bundle/ruby/1.9.1/gems/mysql2-0.3.2/lib/active_record/connection_adapters$[rails307]$ ls
em_mysql2_adapter.rb mysql2_adapter.rb
take mysql2_adapter.rb file from mysql2 gem version 0.2.x and copy it to the above location
now it works for me with just gem 'mysql2' in Gemfile
After trying the solution offered by #eveevans I was still having version issues. Then reading the suggestion by #rubyconvict, I thought instead about using the -v option for gem rather than pushing files about.
Here's what I found eventually resolved my struggle with the dreaded "version of mysql2 (0.3.2)" message on DreamHost:
# in mysql, create example_app & example_app_test ...
# ... for the purposes of this example only, production == development db
rails new example_app --database=mysql --freeze
cd example_app
vim config/database.yml
# change settings for host, user, password ...
# ... database for test (example_app_test) ...
# ... & database for production & development (example_app)
vim Gemfile
# gem 'mysql2', '< 0.3'
gem uninstall mysql2 # if installed: gem list -d mysql2
gem install mysql2 -v 0.2.7
rake db:migrate
From there, I can move onto other RoR fun, like perhaps modifying routes (vim config/routes.rb ... however your mileage may vary).
WARNING: Please use the 0.2.x
releases if you plan on using it in
Rails <= 3.0.x
so in short just use the latest in the 0.2.x branch for the mysql2 gem.
